Reference of 23786-14-3, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 23786-14-3, name is Methyl 4-methoxyphenylacetate belongs to esters-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.

General procedure: The methyl arylacetate (1 equiv.) and p-ABSA (1.3 equiv.) were dissolved in acetonitrile and cooled to 0 C using an ice bath under an argon atmosphere. 1,8-Diazabicycloundec-7-ene (DBU, 1.3 equiv.) was then added to the stirring mixture over the course of 5 minutes. After the addition of the DBU, the reaction mixture continued to stir at 0 C for an additional 15 minutes. Once this allotted time had passed, the ice bath was removed and the reaction mixture was stirred for 24 hours at room temperature. The resulting orange solution was quenched with saturated NH4Cl and the aqueous layer was extracted with diethyl ether (3x). The organic layer was then washed with deionized H2O to remove any residual salts. The combined organic layers were dried over MgSO4 and filtered. The organic layer was then concentrated under reduced pressure. The residue was purified via flash chromatography on silica gel (10:1 Hexanes:EtOAc).

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, Methyl 4-methoxyphenylacetate, other downstream synthetic routes, hurry up and to see.
